"Easy to use, just keep a rag handy for spills. The little blue bit srews in without leaking which I didn't think it would. Just remember no pressure in the system, it doesn't say on the instructions but think about it."

Review 2 for Superconcentrate Central Heating Cleanser 290ml
"I purchased this product while I was in the uk for my home here in France mainly because the instructions are in English and also because Fernox is a great product.To be fair to the product its still early to see if it achieves what i want which is to help unblock some old rads that are silted up.but already it feels like some of the other rads are getting hotter. Would buy this again as its unfair to judge any p roduct on very ols cast iron rads that have never been cleaned out before.e"
